Well, for 1, there are currently NO manufacturers of gasoline DI engines that specifically require a low-SAPS oil in North America that I know of. None of the Hyundai's, GM's, Toyota's, Lexus', Honda's, Mazda's, etc specifically state that they need such oil. The owner's manuals usually state that an ILSAC GF-5 and API SN oil should be used (and of course the recommended grade). Now, we here on BITOG may want to use a low-SAPS oil in a GDI engine due to the perceived benefits proclaimed by Lubrizol with respect to intake valve deposits, but manufacturers have not really embraced this as a requirement yet.
Also, I have never come across ANY gasoline engine (DI or otherwise) with a particulate filter. Can you provide some examples?
Furthermore, the original poster's Honda is a 2009 with the 2.0 L port-injected 4-cylinder engine. It does not in any way require a low-SAPS oil, period. Therefore, it is not required to use the C3 oil that the OP is currently using. He can choose to run an A3 oil and achieve longer drain intervals due to higher starting TBN, and "possibly" better wear protection (I quote that because there were some comments on here at one point that questioned the absolute wear protection of low-SAPS oils, but I cannot confirm nor deny those comments).
